複合管。[Scope of Claim for Utility Model Registration] 1. For propulsion construction method in which the outer peripheral surface and the inner peripheral surface are formed of a reinforced plastic layer, a resin mortar layer is interposed between both surfaces, and a step is provided on the spigot side to reduce the diameter. In this reinforced plastic composite pipe, the outer peripheral surface of the step is covered with a reinforced plastic layer, and the reinforced plastic layer extends into the pipe wall to form an intermediate reinforced plastic layer within the pipe wall. Reinforced plastic composite pipe for construction methods. 2. Scope of Utility Model Registration Claim 1, in which the intermediate reinforced plastic layer formed within the pipe wall extends to the other end (receptacle side) of the pipe, and the reinforced plastic layer and resin mortar layer alternately overlap over the entire length of the pipe. Reinforced plastic composite pipe for the described propulsion method. 3. A utility model registration request in which the intermediate reinforced plastic layer formed in the pipe wall extends over a desired range from the step on the pipe entry side, and the reinforced plastic layer and resin mortar layer alternately overlap only in this part. Reinforced plastic composite pipe for the propulsion method described in scope 1.
